如果其中的一个 node 坏了,相应的另外一个 node 的 replica 将起作用,从而不会造成数据的丢失。Elasticsearch 中的一些重要概念: cluster, node, index, document, shards 及 replica如果一个 index 显示的是红色,表面这个 index 至少有一个 primary shard 没有被正确分配,并且有的 shard 及其相应的 replica 已经...
在有些情况中,我们可以通过设置node.voting_only为true从而使得一个node在node.master为真的情况下,只作为参加voting的功能,而不当选为master node。这种情况为了避免脑裂情况发生。它通常可以使用一个CPU性能较低的node来担当。 在整个Elastic的架构中,Data Node和Cluster的关系表述如下: Document Elasticsearch是面向文...
默认配置会出现这种问题:node1作为指定的master节点可以正常启动, 但是node2、3等更多从节点无法发现master节点,一直在警告 master not discovered yet, this node has not previously joined a bootstrapped (v7+) cluster。。 这是因为上面的9200 - 9202端口只是设置的ElasticSearch的Http端口,默认的集群选举端口是9300...
Elasticsearch是一个分布式搜索和分析引擎,可以处理大量数据。它是用Java编写的,基于Apache Lucene搜索库。
出现关键字:“node-left”;“master left”;“although publication of cluster state version completed ago” 原因分析和解决方案 1、“although publication of cluster state version completed ago” 原因分析:数据节点负载过高,与主节点通信超时引发失联

迁移:融合完成后,通过对ES集群cluster/settings设置exclude属性来进行分片的迁移,当执行了如下API后,ES集群就会自动将自建集群节点上的分片逐步驱逐到云上的节点上来。从而完成分片的搬迁和集群数据的迁移工作。 PUT _cluster/settings { "persistent":{ "cluster.routing.allocation.exclude_name":"{source_node_names}...
